Re: [ebxml-bp] [ebBP] 6/14/2004: WI-21 Pre- and Post Conditions

Monica,

I mentioned last week when John brought this up that I thought
there was an opportunity here to use the ebContext mechanism
to leapfrog this and get to a simple resolution.

I've added use Case #4 to the context proposal to tackle this.

Hopefully this provides a simple and elegant means to achieve
this - where you state a boolean condition in either
beginsWhen / endsWhen declarations - and then point to
an actual context condition in the ebContext instance using
that boolean condition name as effectively the lookup of
the condition you want evaluated (as:setID="ruleName").

The goal here is to give implementers a neat and simple
mechanism in V2.0 BPSS that will cover off most
obvious uses via consistent XML syntax (XPath V1.0).

Thanks, DW
